führen.
Die Erfindung bestehtin der Anwendung eines bei Augenblicksschaltern an sich bekannten Kontakthebels, welcher sich unter dem Einfluss von Feder-oder Gewichtsbelastung zwischen seinen beiden End- stellungen in labiler Totpunktslage befindet, in Kombination mit einem Bimetallstreifen, der lediglich dazu dient, den Hebel in der einen oder andern Bewegungsrichtung über die Totpunktslage hinwegzubringen, worauf die Bewegung durch die Feder rasch zu Ende geführt wird.
In den Fig. 1-3 ist eine Ausführungsform der Erfindung in drei Ansichten teilweise geschnitten darge teilt.
In dem Gestell a. ist der mit einer Nabe b' versehene Hebel h drehbar gelagert. An die : em Hebel

so schnappt der Hebel in die eine oder andere Endlage. Er kommt alsdann an einer der beiden Kontaktoder Ansphlagssehrauben c oder zur Anlage. An der Nabe greift der Bimetallstreifen d an. Dieser
EMI1.3
er besteht, die Nabe, zu drehen. Die Bewegung setzt erst dann ein, wenn der Streifen eine die Kraft der Feder f überwiegende Spannung angeonmmen hat. Sobald die Gleichgewichtslag überschritten ist. führt die Feder den Kontakthebel augenblicklich in die andere Endlage.
Die Eiwärmung kann durch eine darumgewickelte Heizspirale, durch Bestrahlung, oder wenn e@ sich um die Anwendung als Feuermelder oder Fernthermometer handelt, durch die umgebende Luft oder in son, t bekannter Weise bewirkt werden.

to lead.
The invention consists in the use of a contact lever known per se in instantaneous switches, which is located in an unstable dead center position between its two end positions under the influence of spring or weight loading, in combination with a bimetal strip which only serves to hold the lever in one or another direction of movement beyond the dead center position, whereupon the movement is quickly brought to an end by the spring.
1-3, an embodiment of the invention is partially cut in three views Darge shares.
In the frame a. the lever h provided with a hub b 'is rotatably mounted. To the: em lever

so the lever snaps into one or the other end position. It then comes to rest on one of the two contact or attachment screws c or. The bimetal strip d engages the hub. This
EMI1.3
it consists of turning the hub. The movement only begins when the strip has assumed a tension that predominates over the force of the spring f. As soon as the equilibrium position is exceeded. the spring immediately moves the contact lever to the other end position.
The heating of the egg can be brought about by a heating coil wound around it, by irradiation or, if it is used as a fire alarm or remote thermometer, by the surrounding air or in any other known way.
